Kepler-20 d is a rare exoplanet. It lies about 921.6 light-years from Earth, has an equilibrium temperature near 430 K, spans roughly 2.61 Earth radii and weighs about 13.4 Earth masses.
Crammed into a system of five or more planets.
Like any astronomical target, Kepler-20 d is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.
Kepler-20 d scores 33 points on Spacedle's rarity scale, which places it in the rare tier. Another 13 points would lift it into a rarer tier.
That score comes from 5 science badges — Confirmed exoplanet, Sub-Neptune, Multi-planet system, Richly packed system and Found by Kepler — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
